Windshield Pit vs Chip

Windshield Pit vs. Chip: What’s the Difference?

Categories: 

Guide

You are cruising down the highway, and that familiar “ping” against the windshield echoes through the car. Looking up, you discover a small mark – a souvenir from a rogue pebble courtesy of the truck ahead.
 
The question now is: is it just a harmless pit or something more concerning like a chip? You can decide the best action to keep your car safe and your wallet happy by understanding the types of windshield damage.
 

Understanding Windshield Pits

Picture a highway sandstorm peppering your windshield. That is essentially what happens with pitting. Small particles such as sand, dust, or debris from the road can quickly hit your windshield, creating a constellation of small craters on the glass. These seemingly insignificant indentations can accumulate and reduce the quality of your vision.
 
The severity of pitting varies. Pits can be shallow and scattered or deeper and concentrated in specific areas. The location also matters – pits directly in your line of sight require more immediate attention than those on the periphery.
 

Understanding Windshield Chips

Windshield chips are the more dramatic cousins of pits. These occur when a larger object, like a rogue pebble, strikes the windshield with enough force to break through the first layer of glass. They create a visible crack or “starburst” pattern, often accompanied by a small pocket of trapped air between the glass layers. Chips can also cause visual distortions, glare, and safety concerns if they grow too large.
 

Windshield Crack vs Chip: Differences Explained

A quick breakdown of the primary differences between pits and chips is provided below:
 
Depth
 

  • Pits: These are tiny craters etched into the outer surface of the windshield. Their impact is far less dramatic, barely breaching the surface of the protective glass, which is why they appear shallow.
  • Chips: Unlike pits, chips involve deeper penetration. The impact from a larger object crack or breaks through this first layer, creating a visible blemish that can sometimes resemble a “starburst” pattern.

 
Spreading
 

  • Pits: The good news with pits is that they generally stay put. They are unlikely to spread or grow over time because they do not involve a crack through the glass.
  • Chips: Chips, however, pose a massive threat. The compromised first layer acts as a starting point for cracks. Temperature fluctuations, vibrations from driving, or further impacts can cause these cracks to spread. Left unattended, a chip can morph into a larger crack that significantly compromises the windshield’s integrity.

 
Safety Issues
 

  • Pits: Pits typically do not pose a major safety risk despite being visually distracting, especially in certain lighting conditions. Their shallow nature does not weaken the overall structure of the windshield
  • Chips:  Chips are a significant safety concern. They can spread, blocking your view with blind spots or distortions. A large crack weakens the windshield, making it more likely to shatter in a crash.

 
Visual Impact
 

  • Pits: Over some time, these small indentations may increase in number and significantly affect your ability to see clearly, particularly when reflecting sunlight or headlights coming towards you. Nonetheless, distractions are typically minimal, especially when the pits are positioned away from the driver’s immediate view.
  • Chips: Chips can be far more visually disruptive. The crack or “starburst” pattern can obstruct the driver’s view if located within the primary viewing area. Additionally, chips can cause significant glare, making it difficult to see oncoming headlights or navigate in bright sunlight.

 

Repair Options for Pits

Identifying windshield pits early on helps you take steps to address them promptly. A professional polishing treatment can work wonders for minor windshield pitting. Here is what you can expect:
 

  • The Process: The procedure involves a skilled technician using a specific polishing compound and buffing machine to gently flatten the rough spots. This process effectively removes a thin layer from the outer glass surface, reducing the depth and visibility of the pits.
  • Benefits: Polishing is a relatively quick and affordable solution for minor pitting. It can significantly improve the clarity of your windshield, especially when the pits are scattered and do not significantly obstruct your view.
  • Limitations: It is crucial to understand that polishing has its limits. Deep pits or those concentrated in a specific area might not respond well to this treatment. Additionally, polishing removes a limited amount of glass material. Excessive polishing can weaken the windshield over time.

 

Repair Options for Chips

A windshield repair technique called resin injection can be a viable solution for small chips that have not developed extensive cracks. Here is how it works:
 

  • The Process: A qualified technician carefully cleans and prepares the chipped area. Then, they inject a clear, high-strength resin into the chip using a specialized applicator. This resin fills the air pocket created by the impact, preventing further moisture intrusion and halting crack growth. After it cures, the resin practically disappears, fixing the chip and strengthening the area around it.
  • Benefits: Injecting resin is an affordable method to fix minor chips and stop them from escalating into major issues. It is a fairly fast repair procedure that can be finished in under an hour. Furthermore, effective resin injection services can enhance the strength and clarity of the windshield, ensuring optimal visibility for safe driving.
  • Limitations: There are limitations to this approach. Larger chips, especially those with extensive spider cracks, might not be suitable for resin injection. The technician needs enough intact glass around the chip to ensure a proper seal and prevent further cracking. Additionally, the efficacy of resin injection relies on the technician’s skill and experience.

 

Preventive Measures

Dealing with windshield damage is a hassle.  The good news is that there are several proactive steps to minimize the risk of both pitting and chipping, keeping your windshield pristine and your view of the road unobstructed.
 
1. Become a Defensive Driver
 

  • Maintain a Safe Following Distance: This golden rule applies not just to avoiding rear-end collisions but also to safeguarding your windshield. Leaving ample space between you and the vehicle ahead allows you to makeover safely if the car in front throws up debris or suffers a flat tire.
  • Beware of Gravel Trucks: They are notorious for launching a continuous barrage of small rocks towards your car. Try giving them extra room or temporarily switch lanes if you spot one approaching.
  • Avoid Tailgating:  Heavy rain or snow can loosen road debris, increasing the likelihood that it will go airborne and hit your windshield. Increase your following distance during these conditions to reduce the danger of collision.

2. Upgrade Your Windshield Defense System
 

  • Invest in Quality Wipers: Worn-out wiper blades can drag dirt and debris over your windshield, generating scratches that might lead to future cracks. Replace your wipers regularly, using blades specifically designed for your vehicle and climate.
  • Consider a Protective Film: While not a foolproof solution, consider adding a transparent protective film to your windshield to create an extra defense layer against nicks and chips caused by small stones or road debris.

3. Develop Good Habits for Everyday Driving
 

  • Park Smart: Be strategic when parking your car by choosing a covered area or garage whenever available. It protects your windshield from harsh sun rays, extreme heat, and sudden hailstorms, all of which may eventually lead to small cracks or fractures.
  • Frequent Cleaning: Washing your windshield regularly is vital to eliminate dirt, dust, and grime that can cause abrasion on the glass. It also enhances visibility while decreasing the likelihood of minor scratches escalating into larger issues.

 

Conclusion

Understanding the difference between a windshield pit vs. chip might help you make informed decisions about repairing or replacing it. You should seek professional auto glass repair services whether you have minor windshield pits or significant chipping. A skilled technician at an auto glass repair shop can assess the damage and recommend the most suitable course of action, be it a quick polishing treatment or a windshield replacement. 
 
Consulting a professional like the experts at Auto Glass America is the smartest course of action. Their experienced technicians can assess the damage and recommend the most suitable solution, be it a quick and affordable windshield chip repair or a replacement to restore optimal clarity.
